Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a rotary pipe mixing valve. Background Technology

[0002] In gas mixing and proportioning applications, a common method for mixing multiple gases is to connect multiple pipelines to a single chamber simultaneously and install valves on the pipelines. When mixing is required, the corresponding pipeline valves can be opened. Based on the different control methods, they are mainly divided into two categories. One is the automated electronic control scheme, the core of which uses a digital circuit system to drive actuators such as solenoid valves according to a preset program, automatically and precisely controlling the state switching of multiple valves. This method is advantageous for realizing complex proportioning logic and remote control. The other is the manual operation scheme, which relies entirely on operators to manually open and close the valves on each pipeline. This method is direct and does not rely on electricity or complex control systems.

[0003] While both methods are simple and effective in principle, they both have significant limitations. Although the electronic control scheme improves the convenience and automation of control, it introduces a large number of electronic components such as valve drive circuits, controllers, and sensors, significantly increasing the complexity and failure rate of the entire system. On the other hand, while the manual operation scheme has a simple system structure and lower cost, it is cumbersome, time-consuming, labor-intensive, and inefficient. Furthermore, manual operation inevitably suffers from problems such as improper valve opening and closing, misoperation, or forgetfulness due to human factors. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0019] like Figure 1-8 As shown, this utility model provides a rotary pipe mixing valve, including a fixed component 1, a valve stem 2, and a rotary disc 3; the fixed component 1 and the rotary disc 3 are arranged opposite to each other; the valve stem 2 is disposed between the fixed component 1 and the rotary disc 3; one end of the valve stem 2 near the fixed component 1 is detachably connected to the fixed component 1; the other end of the valve stem 2 near the rotary disc 3 is detachably connected to the rotary disc 3. The aforementioned fixed component 1 is provided with a preset number of first pipe holes 4; the aforementioned turntable 3 is provided with the preset number of pipe hole combinations 5; each pipe hole combination 5 includes at least two second pipe holes 6 with the same cross-sectional area; the spacing between each pair of adjacent second pipe holes 6 is the same.

[0020] In some embodiments, the fixing component 1 is a pipeline fixing end and is disc-shaped; the valve stem 2 is a rotatable shaft; the turntable 3 is disc-shaped; the fixing component 1 and the turntable 3 are arranged opposite to each other, and their radii can be the same; the valve stem 2 is disposed between the fixing component 1 and the turntable 3; both the fixing component 1 and the turntable 3 have holes in their centers, and the valve stem 2 can be detachably connected to the fixing component 1 and the turntable 3 through these two holes respectively, that is, the end of the valve stem 2 near the fixing component 1 is detachably connected to the fixing component 1, and the end of the valve stem 2 near the turntable 3 is detachably connected to the turntable 3; The preset number is determined based on the actual number of pipes. Each pipe represents an independent gas or liquid path. In order for the pipe mixing valve to accurately control each fluid path, each path must be provided with an independent, non-interfering connection port, that is, a preset number of first pipe holes 4 are set on the axial surface of the fixed component 1.

[0021] like Figure 1-2As shown, taking a configuration with 4 pipes as an example, the preset quantity is 4. Therefore, the fixed component 1 is provided with 4 first pipe holes 4 for connecting to each pipe respectively; the axial surface of the turntable 3 is also provided with pipe hole combinations 5 corresponding to each pipe, i.e., 4 pipe hole combinations 5; since there are different usage modes in actual use, each pipe hole combination 5 includes at least two, or in other words, second pipe holes 6 with the same cross-sectional area as the number of modes, to cope with different usage modes; and in order to ensure that different second pipe holes 6 do not interfere with each other, when the number of pipes and mode requirements are moderate, the spacing between every two adjacent second pipe holes 6 can be the same; for example, the angle value between every two adjacent second pipe holes 6 can be calculated by the following formula: (1) in, is the angle value between every two adjacent second pipe holes 6; n is the number of pipes; N is the number of patterns.

[0022] In actual design, since the maximum pipe diameter and the distance between two adjacent pipes are known, considering the convenience of installation, in order to avoid interference between different pipe holes and to allow the valve to have extra time to close or open, half a phase can be reserved, that is, half a mode number N+0.5 is added. Thus, the angle value between each two pipe holes can be calculated by combining the calculation formula (1), the number of pipes and the number of modes.

[0023] Simultaneously, combining the known spacing between two adjacent pipes, the maximum pipe diameter, the number of pipes, and the number of patterns, the minimum distribution radius of the pipe holes on turntable 3 is calculated using the following formula: (2) Where d is the distance between two adjacent pipes; D is the maximum pipe diameter; n is the number of pipes; and N is the number of patterns.

[0024] d+D represents the distance from the center of one pipe to the center of the adjacent pipe. The total number of trigger points on turntable 3, i.e., the total number of arc length units that turntable 3 needs to allocate, is therefore the total arc length requirement on turntable 3 is: Since the circumference of the circle is 2πR, we can obtain the calculation formula (2) to calculate the minimum distribution radius. This ensures that the design is flexible enough to adapt to different formulations while maintaining a compact structure, by combining the number of pipes and the number of modes.

[0025] Additionally, based on the known distance between the outer edge of the pipe hole and the edge of the turntable 3... Therefore, the diameter of turntable 3 can be obtained. The calculation formula is as follows: (3) in, R is the diameter of turntable 3; R is the distribution radius; D is the maximum pipe diameter of the pipe hole; The distance between the outer edge of the pipe hole and the edge of the turntable 3 is referred to as the turntable edge distance.

[0026] In other embodiments, the preset quantity can be set automatically based on the actual number of pipes used.

[0027] In this invention, each of the first pipe holes 4 is a circular hole; each of the second pipe holes 6 is a circular hole.

[0028] In some embodiments, in order to adapt to the shape of the pipe, each first pipe hole 4 is a circular hole and each second pipe hole 6 is a circular hole.

[0029] In other embodiments, the shape of each first pipe hole 4 and each second pipe hole 6 can be set according to the actual shape of the pipe.

[0030] In this invention, the centers of all the aforementioned first pipe holes 4 are located on the same circle; the centers of all the aforementioned second pipe holes 6 are located on the same circle. Both the first and second pipe holes are circular in shape, matching the shape of the pipes, thus improving the ease of installation and sealing reliability of the rotary mixing valve.

[0031] In some embodiments, such as Figure 2 , Figure 6-8 As shown, taking an actual system with four pipes and three operating modes as an example, the four pipe hole combinations 5 are evenly distributed in the four quadrants of the circumference. Therefore, the centers of all the second pipe holes 6 are on the same circle, and the cross-sectional area occupied by each pipe hole combination 5 on the turntable 3 is also the same. Since the positions of the first pipe holes 4 correspond to the positions of the pipe hole combinations 5, the centers of all the first pipe holes 4 are on the same circle. Setting the centers of the first pipe holes on the fixed component and the centers of the second pipe holes on the turntable on the same circle ensures that the flow channels on the turntable can be precisely aligned with the pipe holes on the fixed component with the shortest path and the least fluid resistance, achieving efficient flow path switching. Moreover, all holes can be processed in one clamping, greatly ensuring the relative positional accuracy and concentricity between holes, reducing manufacturing costs and assembly difficulty.

[0032] In this invention, the centers of all the aforementioned first pipe holes 4 are on the same straight line; the centers of all the aforementioned second pipe holes 6 are on the same circle.

[0033] In some embodiments, such as Figure 3As shown, when there are many pipes and pattern requirements, it is possible to distribute some small-diameter second pipe holes 6 on the line connecting the center of the large-diameter second pipe hole 6 to the center of the turntable 3. The small-diameter second pipe holes 6 must be within the area enclosed by the tangent line connecting the center of the turntable 3 to the edge of the large-diameter second pipe hole 6. In this way, the centers of all the second pipe holes 6 in each pipe hole combination 5 are still on the same circle. In each pattern, since the small-diameter second pipe holes 6 must be within the area enclosed by the tangent line connecting the center of the turntable 3 to the edge of the large-diameter second pipe hole 6, the centers of the first pipe holes 4 on the corresponding fixed parts 1 are all on the same straight line. When calculating the angle value between two adjacent second pipe holes 6, the above formula (1) still applies, except that different maximum pipe diameters are used when calculating the outer and inner circles. When there are many pipes and different pipe patterns, the small diameter orifices are moved radially inward to effectively utilize the central area of ​​the turntable. This significantly increases the channel density without increasing the turntable diameter, achieving a compact structure, reducing pipe partitions, and making the flow channels more direct by radial arrangement. This reduces bends and lengths, which helps to reduce overall flow resistance. It also enables the coordination of flow rate and pressure drop in each path by adjusting the orifice diameter of different radii, thereby improving the system's flow performance.

[0034] In other embodiments, the center of all the first pipe holes 4 can be set according to the actual situation.

[0035] In this utility model, the second pipe hole 6 includes a third pipe hole 7 and a fourth pipe hole 8; the third pipe hole 7 is a circular hole; the fourth pipe hole 8 is a circular hole; the cross-sectional area of ​​the third pipe hole 7 is the same as the cross-sectional area of ​​the fourth pipe hole 8.

[0036] In some embodiments, such as Figure 4 As shown, each pipe hole assembly 5 includes at least two second pipe holes 6; specifically, the at least two second pipe holes 6 can be divided into a third pipe hole 7 and a fourth pipe hole 8. Both the third pipe hole 7 and the fourth pipe hole 8 are circular holes, and the cross-sectional area of ​​the third pipe hole 7 is the same as that of the fourth pipe hole 8. The third and fourth pipe holes are distinguished according to their functions, which facilitates switching of flow paths in different operating modes.

[0037] In this invention, the rotary pipe mixing valve further includes an elastic component 9; the shape of the elastic component 9 matches the shape of the third pipe hole 7; the elastic component 9 is spirally distributed along the inner surface of the third pipe hole 7.

[0038] In some embodiments, such as Figure 4As shown, the third pipe hole 7 is a blind hole, i.e., a pipe hole that is not used. Therefore, an elastic component 9 is needed to cooperate with the blocking element 10 to block it, thereby preventing accidental selection. The elastic component 9 can be a spring. The rotary mixing valve also includes a spring, the shape of which matches the shape of the third pipe hole 7. Therefore, the spring is spirally distributed along the inner surface of the third pipe hole 7. By setting the elastic component inside the third pipe hole, a continuous and stable thrust is provided to the blocking element, ensuring that it can reliably seal the corresponding first pipe hole when it is not in the working phase, and buffering the impact of movement, thus extending the service life of the rotary mixing valve. By confining the elastic component inside the third pipe hole, the drive, reset, and buffering functions are all built into the rotary body, eliminating the need for complex external mechanisms, greatly simplifying the overall design, and realizing the modularization and miniaturization of functional components.

[0039] In other embodiments, the elastic member 9 can be configured according to the actual situation.

[0040] In this invention, the rotary pipe mixing valve further includes a blocking element 10; the shape of the blocking element 10 matches the shape of the third pipe hole 7; the blocking element 10 is detachably connected to the third pipe hole 7 via the elastic member 9.

[0041] In some embodiments, such as Figure 4 As shown, the rotary mixing valve also includes a blocking element 10, the shape of which matches the shape of the third pipe hole 7. Therefore, the blocking element 10 is detachably connected to the third pipe hole 7 via elastic elements distributed on the inner surface of the third pipe hole 7. By setting the blocking element, an adaptive seal is achieved in cooperation with the elastic component, blocking the flow channel while ensuring uniform wear, thus extending the service life of the rotary mixing valve.

[0042] The aforementioned blocking element 10 is a spherical element; the diameter of the aforementioned blocking element 10 is larger than the diameter of the aforementioned third pipe hole 7.

[0043] In some embodiments, the blocking element 10 can be a sphere / ball. Taking a sphere as an example, the diameter of the blocking element 10 is larger than the diameter of the third pipe hole 7. Therefore, when in a non-selected phase, i.e., when the first pipe hole 4 on the fixed component 1 is aligned with the third pipe hole 7, the blocking element 10 in the third pipe hole 7 (blind hole) covers the pipeline due to the thrust of the elastic component 9, thus achieving a closing effect. During rotation, the blocking element 10 rolls close to the surface of the fixed component 1. When it reaches the phase, a portion of the blocking element 10 falls into the pipeline, which serves as the position mark and locking function as shown in the figure, clarifying the feel and providing a prompt. The diameter of the blocking element is larger than the diameter of the third pipe hole, ensuring that the blocking element always covers an area larger than the third pipe hole, forming a reliable line contact or surface contact sealing band. Even under vibration or slight wear, the spring force of the elastic component can maintain the seal, completely preventing internal leakage or cross-contamination. Furthermore, the interference design in terms of size provides a compensation margin for machining errors, alignment deviations, and long-term wear, significantly improving the reliability of the seal and the service life of the rotary pipe mixing valve.

[0044] In other embodiments, the blocking element 10 may also be a pin or key that functions similarly to a ball or marble, and may be configured according to the actual situation.

[0045] In this utility model, the fixing component 1 is provided with a first through hole 11, and the shape of the side of the valve stem 2 near the fixing component 1 matches the shape of the first through hole 11; the valve stem 2 is detachably connected to the fixing component 1 through the first through hole 11.

[0046] In some embodiments, such as Figure 5 As shown, the fixed component 1 is provided with a first through hole 11, which can be located at the center of the fixed component 1. The valve stem 2 can be a rotating shaft of equal diameter and length. The shape of the side of the valve stem 2 closest to the fixed component 1 matches the shape of the first through hole 11. The valve stem 2 is detachably connected to the fixed component 1 through the first through hole 11. By providing a high-precision support and rotation center for the valve stem through the first through hole on the fixed component, it ensures that the turntable and the fixed component always maintain a coaxial relationship. The valve stem directly transmits torque to the turntable through the first through hole to achieve the switching of different working phases.

[0047] In other embodiments, the first through hole 11 may be provided at other locations on the fixing component 1 as needed.

[0048] In this utility model, the turntable 3 is provided with a second through hole 12, and the shape of the valve stem 2 on the side near the turntable 3 matches the shape of the second through hole 12; the valve stem 2 is detachably connected to the turntable 3 through the second through hole 12.

[0049] In some embodiments, such as Figure 5 As shown, the turntable 3 is provided with a second through hole 12, which can be located at the center of the turntable 3. The valve stem 2 can be a rotating shaft of equal diameter and length. The shape of the side of the valve stem 2 closest to the turntable 3 matches the shape of the second through hole 12. The valve stem 2 is detachably connected to the turntable 3 through the second through hole 12. By providing a second through hole on the turntable, the turntable and the fixed component are precisely matched, the rotation center of the turntable is determined, and all the second pipe holes on it can always maintain a very high coaxiality with the first pipe holes on the fixed component, achieving precise docking and preventing leakage.

[0050] In other embodiments, the second through hole 12 may be provided at other locations on the turntable 3 as needed.

[0051] The working principle of the rotary pipeline mixing valve of this utility model is as follows: In the design, taking a pipe with 4 pipes and 3 working modes as an example, each pipe is provided with 3 pipe holes, and each pipe hole combination 5 is evenly distributed in the 4 quadrants of the circumference, that is, each pipe hole combination 5 occupies 90°, and according to formula (1), the angle between two adjacent second pipe holes 6 in each pipe hole combination 5 is calculated to be 25°; among them, the largest pipe diameter among the 4 pipes is 6mm, and the installation gap between two adjacent pipe holes is required to be no less than 1mm, so it can be substituted into formula (2) to calculate the minimum distribution radius as 16mm. According to the preset turntable edge distance, the radius of the turntable 3 is calculated to be about 40mm; it is designed as three working modes, that is, three working phases, of which phase one is pipe 1 + pipe 2 flow, phase two is pipe 2 + pipe 3 flow, and phase three is pipe 4 flow. According to the design requirements, each pipe hole combination 5 is provided with a third pipe hole 7, that is, a blind hole, using elastic component 9 and blocking element 10.

[0052] During rotation, when it reaches phase one, as... Figure 6 As shown, each pipe hole assembly 5 is equipped with a third pipe hole 7 and a fourth pipe hole 8 according to actual needs; Figure 6 In the diagram, A / B / C / D represent the second pipe hole 6 selected in each pipe hole combination 5 when the rotary type 3 pipe mixing valve is in phase one. The pipe hole combination 5 corresponding to A is pipe 1, the pipe hole combination 5 corresponding to B is pipe 2, the pipe hole combination 5 corresponding to C is pipe 3, and the pipe hole combination 5 corresponding to D is pipe 5. Figure 6 As can be seen, A / B is the fourth pipe hole 8, and C / D is the third pipe hole 7, at which point the flow of pipe 1 + pipe 2 is achieved; When rotated to phase two, as Figure 7 As shown, each pipe hole assembly 5 is equipped with a third pipe hole 7 and a fourth pipe hole 8 according to actual needs; Figure 7 In the diagram, A / B / C / D represent the second pipe hole 6 selected in each pipe hole combination 5 when the rotary type 3 pipe mixing valve is in phase two. The pipe hole combination 5 corresponding to A is pipe 1, the pipe hole combination 5 corresponding to B is pipe 2, the pipe hole combination 5 corresponding to C is pipe 3, and the pipe hole combination 5 corresponding to D is pipe 5. Figure 7 As can be seen, B / C is the fourth pipe hole 8, and A / D is the third pipe hole 7, thus realizing the flow of pipe 2 + pipe 3; When rotated to phase three, as Figure 8 As shown, each pipe hole assembly 5 is equipped with a third pipe hole 7 and a fourth pipe hole 8 according to actual needs; Figure 8 In the diagram, A / B / C / D represent the second pipe hole 6 selected in each pipe hole combination 5 when the rotary type 3 pipe mixing valve is in phase three. The pipe hole combination 5 corresponding to A is pipe 1, the pipe hole combination 5 corresponding to B is pipe 2, the pipe hole combination 5 corresponding to C is pipe 3, and the pipe hole combination 5 corresponding to D is pipe 5. Figure 8 As can be seen, D is the fourth pipe hole 8, and A / B / C are the third pipe holes 7, thus realizing the flow of pipe 4.

[0053] The beneficial effects of this utility model are: This utility model discloses a rotary mixing valve, comprising a fixed component, a valve stem, and a rotary disc. The fixed component is disposed opposite to the rotary disc. The valve stem is disposed between the fixed component and the rotary disc. One end of the valve stem near the fixed component is detachably connected to the fixed component. The other end of the valve stem near the rotary disc is detachably connected to the rotary disc. The fixed component has a predetermined number of first pipe holes. The rotary disc has the predetermined number of combinations of pipe holes. Each combination of pipe holes includes at least two second pipe holes with the same cross-sectional area. The spacing between any two adjacent second pipe holes is the same. By providing the same number of first pipe holes and combinations of pipe holes on the fixed component and the rotary disc, different numbers of pipes can be accommodated. Each combination of pipe holes has multiple second pipe holes with the same cross-sectional area to accommodate different operating modes. The equal spacing between any two adjacent second pipe holes avoids interference and enables rapid switching between different pipe combinations. When there are many pipes and different modes, the small-diameter holes are moved radially inward to effectively utilize the central area of ​​the turntable. This significantly increases the channel density without increasing the turntable diameter, achieving a compact structure. Elastic components and blocking elements are set to set the third pipe hole, enabling rapid switching between multiple working modes, and unselected pipes can be closed quickly.
